SJA>> Torchwood. I loved that show. I think what made SJA work so well is it's kept the soul of what made Doctor Who so fun. Only it was packaged for children. Torchwood rejected what made Doctor Who charming and instead relied on things that adults would find "appealing". Things like graphic violence, sex, gay relationships, curse words and such. Torchwood kept the alien of the week plot for the first two seasons mostly.
Admittedly I always like Maria over Rani.
